Dymaxion Diamond Core Drill for Concrete 26 x 450mm 1-1/4" UNC Fitting

Dymaxion is an Australian brand of abrasive cutting and grinding discs and diamond core drilling products, supplying tradespeople, fabricators, and construction teams with high-volume cutting and drilling consumables for angle grinders, stationary cut-off machines, and rotary core drill rigs. Their range covers steel cutting, stainless steel (INOX) cutting, masonry cutting, metal grinding, and diamond core drilling for concrete and brick.

Dymaxion diamond core drill bits are used with rotary core drilling rigs to produce clean, accurate through-holes in concrete and brick without the cracking and spalling caused by hammer drills or masonry bits. The diamond-impregnated crown cuts through aggregate and reinforcing to produce a smooth cylindrical hole suited to pipe penetrations, cable routes, and anchor installations in structural concrete.

Where this product is used

Diamond core drills are used wherever clean, accurate holes are required in concrete or masonry:

• Building services and plumbing installations where pipe and conduit penetrations through concrete floors and walls must be clean and accurate.
• Structural and civil engineering where core holes are drilled for anchor bolts, dowels, and post-installed reinforcing.
• Renovation and fitout work where core drilling is required through existing concrete slabs and masonry walls without cracking.

Selecting the right option

Select by core diameter to match the required hole size — allow for the bit outer diameter being larger than the finished hole. Confirm the bit shank matches your core drill rig's spindle interface. Dymaxion diamond cores are available in concrete and concrete/brick variants — the concrete/brick version is the more versatile choice where the material mix is unknown. Always use water cooling during drilling to extend bit life and prevent overheating of the diamond segments.
